Separate keybind for laser and light

I previously found myself constantly fiddling with the light/laser button on the keyboard whenever moving through the dark, underground part of the office map. At that point in time, I used to mainly aim with the laser (now I just stopped using the laser alltogether in favour of the tech sight, but leaving the ability to show my teammates who exactly I am shooting is a bit of a bummer), and having to fiddle with it to disable the light afterward left me hoping for a possibilty of a separate keybind, that would allow to toggle light/laser independently from one another. It doesn’t need to be bound by default, I’d just like an option of setting up a keybind individually for either action.
